I think "chage" only allows caducity for, at least, one day. You’re pushing the limits of my memories of latin class, but if I understand what you’re asking, you want to set the expiration of a password to a specific hour, not day. The password age, minimum age and maximum age fields in /etc/shadow are stored as an integer in days, so no, I don’t believe you can set it to a specific hour. -- Jonathan Billings <billings at negate.org>
